Description

Technical Field

[0001] The utility model relates to a silk-screen tooling with automatic fixed position. Background Art

[0002] Screen printing refers to using a silk screen as a base plate and making a screen printing plate with images and texts through a photosensitive platemaking method. Screen printing has the advantages of large batches, low prices, bright colors, long shelf life, and fast delivery, and is recognized by more and more industries. At present, during production, companies will disassemble and replace the screen printing grid according to the needs of printing different patterns. The disassembly and replacement process of the screen printing grid requires the operator to loosen the screws, then remove the screen printing grid, install the new screen printing grid, and then tighten the screws. The whole process is time-consuming and requires manual alignment. When the operator loosens and tightens the screws to ensure that the screen printing grid is completely fixed, it is easy to use excessive force to cause the screws to slip and be damaged. Utility Model Content

[0003] The purpose of the utility model is to overcome the above problems. We provide a screen printing tool with automatic fixed position, which solves the problem of excessive time consumption in disassembling and replacing the screen printing grid frame, and replaces the screw fixation to solve the problem of screw slippage.

[0004] To achieve the above-mentioned purpose, the utility model provides a silk-screen tooling with automatic fixed position, which includes a mounting body, a lower pressure plate, a driving cylinder and a trigger switch. The mounting body is arranged in a mounting groove with a front opening, and "L"-shaped positioning parts are arranged on the left and right sides of the mounting groove. The trigger switch is arranged in the mounting groove and is located behind the positioning part. The elastic trigger end of the trigger switch faces the opening direction of the mounting groove. The lower pressure plate is arranged near the top of the mounting groove and is located above the two positioning parts. The driving cylinder is used to drive the lower pressure plate to move up and down. When the trigger switch is triggered, the driving cylinder drives the lower pressure plate to be pressed down.

[0005] In one or more embodiments, the trigger switch is a micro switch, and the micro switch is fixed to the mounting body by screws.

[0006] In one or more embodiments, an arc-shaped transition section is provided between the front end surface and the inner side surface of the positioning portion.

[0007] In one or more embodiments, the lower pressure plate includes a base and a plurality of connecting bolts, one end of the connecting bolt is threadedly connected to the top of the base, the other end of the connecting bolt passes through the top of the mounting body and is connected to the connecting seat, and the cylinder shaft of the driving cylinder is connected to the connecting seat.

[0008] In one or more embodiments, a non-slip rubber layer is fixed on the bottom surface of the base, and a plurality of raised ribs are provided on the bottom end surface of the non-slip rubber layer.

[0009] In one or more embodiments, the mounting body is made of stainless steel or aluminum alloy.

[0010] Compared with the background technology, the utility model has the following effects: the screen printing tooling adopts automatic clamping by a cylinder, and is provided with a positioning part to guide the operator to position the screen printing grid frame, which greatly shortens the disassembly and replacement time of the screen printing grid frame, and does not need to be fixed by screws, so there is no problem of screw slippage. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 It is a schematic structural diagram of the silk-screen tooling of an embodiment of the utility model. DETAILED DESCRIPTION

[0012] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments and drawings. The embodiments are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0013] See attached Figure 1 The present application provides a screen printing tooling with automatic fixed position, which includes a mounting body 1 made of stainless steel or aluminum alloy, a lower pressure plate, a driving cylinder 2 and a trigger switch 3. The mounting body is arranged in a mounting slot with an opening on the front side, and an "L"-shaped positioning part 4 is arranged on the left and right sides of the mounting slot. The two positioning parts are used to position and fix the left and right sides of the screen printing grid frame to limit the left and right movement of the screen printing grid frame. The trigger switch 3 is arranged in the mounting slot and is located behind the positioning part 4. The elastic trigger end 31 of the trigger switch 3 faces the opening direction of the mounting slot. When the operator pushes the screen printing grid frame into the mounting slot, the trigger switch 3 is in the state of being pressed. When the screen printing grid is installed in the groove, the screen printing grid will touch the trigger switch. The lower pressure plate is arranged near the top of the installation groove and above the two positioning parts 4. The driving cylinder 2 is used to drive the lower pressure plate to move up and down. When the trigger switch 3 is triggered, the driving cylinder 2 drives the lower pressure plate to press down, fixes the left and right sides of the screen printing grid through the two positioning parts, and then presses and fixes the screen printing grid through the lower pressure plate, so as to fix the screen printing grid. During the whole operation process, the operator only needs to push the screen printing grid into the installation groove, and then control the driving cylinder to press and hold the screen printing grid through the trigger switch, which has the advantage of simple operation. It should be noted that the driving cylinder is externally connected to a control switch, which is used to cut off the air source of the driving cylinder and relax the driving cylinder, which is used for operation when disassembling the screen printing grid.

[0014] The trigger switch 3 is a micro switch, which is fixed to the mounting body 1 by screws. The micro switch is a common trigger switch, which has high reliability, small size and low price.

[0015] An arc-shaped transition section 41 is provided between the front end surface and the inner side surface of the positioning portion 4. The arc-shaped transition section can guide the installation of the screen printing grid frame, so that the operator can more easily install the screen printing grid frame in the correct position.

[0016] The lower pressure plate includes a base 5 and a plurality of connecting bolts 6, one end of the connecting bolt is screwed to the top of the base, and the other end of the connecting bolt passes through the top of the mounting body 1 and is connected to the connecting seat 7, the cylinder shaft of the driving cylinder 2 is connected to the connecting seat, and the number of driving cylinders is preferably two, and the cylinder shafts of the two driving cylinders are respectively connected to the two ends of the connecting seat.

[0017] A non-slip rubber layer 8 is fixed on the bottom surface of the base 5, and a plurality of raised ribs are arranged on the bottom end surface of the non-slip rubber layer to prevent the surface of the screen printing grid from being scratched or worn when the lower pressing plate is pressed down, thereby protecting the frame of the screen printing grid.

[0018] The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed in the present invention should be included in the protection scope recorded in the claims.
